Read full descriptionHide full description
Flashd is the bouldering and climbing tracker built for real sessions. Log every route with your grade, attempts, and whether you topped, flashed, or failed, then review your stats when the session ends. TWO TRACKING MODES Pick the flow that fits your session. Timed mode runs a built-in timer for every route so you can see exactly how long each send takes. Quick mode lets you tap to log routes without a timer, perfect for fast sessions or when you just want the count. SESSION STATISTICS After every session, see your topped percentage, flash rate, total points, and highest grade. Track your improvement across sessions with French (4A to 9A) and Hueco (V0 to V17) grading systems. CUSTOM GRADING SYSTEMS Climbing at a gym with its own colour or grade names? Create a custom grading system for your gym or yourself. Each custom grade maps to a French or Hueco equivalent, so your points and stats stay consistent no matter where you climb. SCAN ROUTES WITH AI Snap a photo of the wall and Flashd detects the routes for you, with grades and hold colours. Tweak anything the AI got wrong, then save the routes for your whole gym to log in one tap. EARBUD TRACKING Use your earbud buttons to log routes phone-free. Control your entire bouldering session without touching your phone. (Timed mode) ACHIEVEMENTS Unlock achievements as you climb. Hit milestones for sessions, flashes, grades, and more. GYM LOCATIONS Find nearby climbing gyms and attach sessions to a location so your history stays organised. RANKINGS Compare your grades, points, and flash rates with friends and climbers at your gym. See where you stand on the leaderboard. CLIMB WITH FRIENDS Add friends, share sessions, and see how your climbing stacks up. Free to download. Get on the wall.

TreadLog quietly records the running habit you build on the treadmill. There are plenty of outdoor GPS running apps, but few made for people who run on a gym treadmill. TreadLog focuses on indoor treadmill running only. When your workout ends, just snap a photo of the console. It reads your distance, time, calories, incline, and speed and fills in a log card for you. OCR auto-fill from a console photo Photograph your treadmill console and TreadLog recognizes the on-screen numbers (distance, time, calories, incline, speed) to fill the entry automatically. Recognition runs entirely on your device. If anything is misread, fix it right there in a tap. Quick manual entry too No photo? Just type in distance and time and you're done. You can add outdoor runs by hand as well โ fast and lightweight. Calendar heatmap See when and how much you ran at a glance. The more you ran on a day, the deeper the color, so your monthly pattern jumps out instantly. A monthly summary of runs, distance, and time is included too. Streaks Watch your consecutive running days add up and keep the momentum going. Missed a day? That's okay โ just start again. Stats & pace trend View your all-time cumulative distance, time, and run count, and see how your pace is improving on a trend chart. A weekly distance graph and a weekly goal keep this week's progress in check. Light & dark themes Follow the system setting or pick light or dark yourself, so early-morning or late-night sessions stay easy on the eyes. Your data stays on your phone No sign-up, no login, no server. Every record is stored only on your device. Switching phones? Back up with .zip export and import. A light, quiet treadmill running journal โ manage your indoor running and cardio logs cleanly with TreadLog, and take today's step.
